mercury (Chemistry Operations, 2003). It is an element that is apparently quite unique and one that is used in many applications. The following paper examines cesium and offers an overview
of the element. Cesium The symbol for cesium is Cs and it resides at the number 55 on the atomic chart (Gagnon, 2008). Its atomic weight is 132.9054519
and its melting point is at "28.44?C or 83.19?F" (Gagnon, 2008). It possesses a boiling point that is quite high at "671?C or 1240?F" (Gagnon, 2008). The density of cesium
resides at 1.93 grams for a cubic centimeter and its classification is metal (Gagnon, 2008). The name cesium is derived "from the Latin word for sky blue, caesius" (Gagnon, 2008).
It is also something that is found in very few areas in the world. It is noted, for example, that "One of the worlds richest sources of cesium is located
at Bernic Lake, Manitoba. The deposits are estimated to contain 300,000 tons of pollucite, averaging 20% cesium" (Chemistry Operations, 2003). Cesium, for the most part, is obtained and taken
from a mineral called pllucite (Gagnon, 2008). Getting pure cesium, however, is a difficult task in light of the fact that cesium ores are often riddled with rubidium which is
an element that is quite similar, chemically, to cesium (Gagnon, 2008). As such in order to get the pure cesium out the two ores are crushed and then heated to
650C along with sodium metal (Gagnon, 2008). This results in the formation of an alloy which can be separated (Gagnon, 2008). It is separated in "a process known as fractional
distillation. Metallic cesium is too reactive to easily handle and is usually sold in the form of cesium azide (CsN3)" (Gagnon, 2008). Any cesium that exists in this form is
